Q-Free has collaborated with Slovenian road operator Dars in the deployment of a new cooperative ITS (C-ITS) network in the eastern European country's capital, Ljubljana.

The system will enable equipped Volkswagen vehicles to receive in-car notifications such as traffic incidents, construction zones, low visibility alerts, and wrong-way driver warnings.

The new network sees 25 roadside units (RSUs) on more than 100km of Ljubljana’s major ring-road. These RSUs will transmit information to VW drivers, while receiving traffic flow information from them at the same time. 

Slovenia sits between Austria, Croatia, Hungary and Italy and is on a key freight route between the European nations. Q-Free says traffic volume, particularly around Ljubljana, has increased over the last few years, with some estimates suggesting a 5% annual rise. 

Q-Free and Dars have done something together on a smaller scale before: in 2018, a local pilot used nine RSUs with a central management system.

In this new deployment, Dars will also use five vehicle-mounted mobile units, probably around workzones and traffic incidents. 

“We put a high value on our relationship with Dars and though this solution is not part of our commercial portfolio, we decided to develop a customised solution that would exactly fit their needs,” explains Q-Free CEO Mark Talbot.

“I’m proud of our team for recognising that we’re not just in the traffic management business, we’re in the relationship business."

    The Texas Transportation Institute's Jerry Ullman talks about the state of the art in work zone safety in the US. Work zones are places where, perhaps more than anywhere else on the road network, mobility and safety are strongly linked. Historically, field crews and contractors wanted vehicles in work zones to be moving as slowly as possible, assuming that made conditions the safest for work crews. We are though starting to see a shift in such thinking with the realisation that excessive delays or slow-down

    A common assumption, even amongst informed observers, is that there’s but a handful of urban charging schemes in operation around the world and scant prospect of that changing any time soon. Larger city-sized schemes such as Singapore, London and Stockholm come readily to mind but if we take a wider view and also consider urban access control and Low Emission Zones (LEZs) then the picture changes rather radically. There is a notable concentration of such schemes in Europe but worldwide the number is comfort
